It is easy to overlook, and that is precisely what makes it interesting. The site is a rath, the most common type of ringfort, essentially a circular area of raised ground surrounded by an earthen bank and an external fosse, which is a shallow defensive ditch. Thousands of these were built across Ireland between roughly the sixth and tenth centuries, serving as the fortified farmsteads of farming families and local chieftains. This one sits quietly in the landscape, its origins largely unreadable to the casual eye.

The structure measures 33.6 metres in diameter, enclosed by a bank of earth and stone between 3.6 and 4 metres wide, though only around 0.4 metres high, worn down considerably over the centuries. The external fosse, between one and two metres wide and no more than 0.3 metres deep in places, survives only in fragments. It can be made out from the south-east and south, and again from the south-west and west, but not from the northern arc, where time and agricultural activity have apparently erased it. Most telling of all, the original entrance can no longer be identified. Whatever threshold once marked the way in has been absorbed into the surrounding ground without leaving a clear trace.
